.V SPECIFICATION forming part of Letters Patent No. 271,754, dated February 6, 1883.

Application filed December 14, 1882. (No model.) i

To all whom it may concern:

Be it known that we, GEORGE WlLDEY and ALPHEUs ROLLINs, both of Brooklyn, in the State of New York, have invented `an Improvement in Presses, of which the followingsis a specification.

1n Letters vPatent No. 242,258 a machine adapted to compressing tobacco into plugs is described and shown, in which the mold is formed of an adjustable back plate, a bottom,

movable ends, and a hinged apron forming the front, and theloose tobacco placed within such mold is compressed intoa plug by a vertically-moving plunger actuated by arms and a Athe main shaft is coupled with the drivingpulley and rotates with it, and motion is given by gearing to a second shaft` provided with eccentrics that act through rods and a crosshead to raise and lower the plunger. A latch holds the levers when the drivingpulley is coupled to its shaft, and arms npon'the second shaft disconnect the latch at 4the extreme upi ward and downward, movements of the plunger and stop the t machine automatically at these times. A lifter raises the plug of tobacco from the mold when the plunger is raised.

In the drawings, Figure 1 is an elevation at the rear of the machine, part of the back plate of the mold being removed. Fig. 2 is a section at the line w' x. Fig. 3 is a section at the line y y, with the plunger down. Fig. 4 shows the position of the latch when the main shaft is not coupled to the driving-pulley, and Fig. 5 the position of said latch when the drivingpulley and shaft are coupled.

The side frames, a a, support a table, b,and are'to be of a size and shape adapted to rcceive the parts hereinafter set forth.

The plate c, forming the back of the mold,

the movable end pieces,cl d, the bottom dand the hinged apron e, forming the front of the mold, and themeans forV closing and opening said mold, are similar to corresponding parts in aforesaid Letters Patent, and ourinvention does not relate thereto, and a reference is lhereby made to said patent for a description of these parts.

fis the main shaft, supported in the side frames, and carrying the loose pulley h, that is revolved continuously.` y

is the second shaft, that is 'rotated by means of the gearing 2 3 4 5 and intermediate shaft, k, lwhen the main shaft is coupled to its driving-pulley.

At the outer ends of the shaft i are eccentrics, l Z, from,v which extend rods Z' l to the cross-head m, to which the plunger n is connected by the bolt 6. The ends of the crosshead move in vertical slots iu the guides o, secured to the Lipper part of the side frames, c. p is a clutch fitted to slideupon a feather ou the main shaft f, and said clutch is con-` nected to the levers q and r by the rods s.

t is a notched latch, pivoted at 7, and kept in contact with the upper end of the lever r arms upon a hub ou the shaft t.

i The operation of the machineis as follows The operator places the loose tobacco in the with teeth on the hub of the driving-pulley h,

so that the shaftsf, 1:,and t' are setin motion,

land the plunger n is brought down by the cccentrics l, rods l', and Across-head m to compress the tobacco in the mold. The leverr havingbeen moved by the action of the lever q, its end is caught by thelatch I, as shown in Fig. 5, so that the latch prevents the clutchp being ldisconnected from the driving-pulley, and obviates the necessity of the operator keeping his foot upon the lever c. The shaft t' makes one half-revolution during the descent of the plunger n, and as it completes this halfrevolution the arm 10 comesin' contact wit-h the latch t, pushing it back andseparating it from the lever 13a-nd the spring 10 draws the levers q and r, rods s, and clutch p back into IOO the position shown in Fig. 1 and uncouples the shaftffrom the driving-pulley h, stopping the press. When the pressure has been applied upon the tobacco and the press stops, then the operator opens the molds and again presses-upon the lever v to couple the shaftf and hold the lever 'r by the latch t. The shaft i then makes another half-revolution and the plunger n is raised. The arm 9 now disconnects the latch tfrom o' and the machine is again stopped; but just before the plunger reaches its extreme upward movement a cam, w, upon the Wheel 5 acts upon the lifter w', which raises the plug ot tobacco out of the mold.

In order to adjust the plunger with reference to the thickness of plug to be formed, the ends of the rods l l are made with right and left hand screw-threads, entering correspondingly-'threaded parts in sockets upon the eyes Z2 and the straps of the eccentrics Z, so that by turning said screw-rods the plunger is raised or lowered, as desired.

We claim as our invention- Y l. The shaftf, loose pulley thereon, clutch p, rod s, levers q and lr, and latch t, in combination with the shaft i, arms 9 and 10, mold, plunger, and eccentrics Z, and rods Z, for actuating the plunger', substantially as and for the purposes specified.

lifter w',- in combination With means for rotating said shaft, the mold and plunger, and mechanism for actuating said plunger, substantiall7 as and for the purposes specified.`

3. In a press for compressing tobacco into plugs, the combination of a mold, plunger, cross-head, eccentrics, adjustable connectingrods` between the eccentrics and cross-head, and means for rotating the shaft and eccentrics, and an automatic stop-motion, substantially as and for the purposes specified.

4. In a press for plug-tobacco, a mold with movable sides and a plunger for the same, in combination with a revolving shaft and mechanism for moving the plunger, and an automatic stopmotion that arrests the movement of the plunger after the pressure has been applied, and also When the plunger is raised for filling the mold, substantially as specified.
